Clash #39 Shaft Metal Change
Titanium is gunmetal/silver color and the hole at the end sits flat in the same direction as the flat upper edge.
On original Aluminum (coated tan color), the hole is angled away from the direction of the flat upper edge as shown.
We are using a sample of the 39-CLA4000 but this applies to the entire series.
Inventory
This appears to be just sizes CLA2000 thru CLA4000, as the CLA5000 and up have a different style of shaft setup.
Part
39-CLA2500 is no longer available in aluminum.
